When I place my battery in my 56-volt, 30-minute CH5500 charger, the 25% indicator light briefly flashes, then all four level indicator lights come on green as if the battery is fully charged but it is not. I have unplugged, waited a few minutes, and plugged it back in several times, which has worked in the past to solve a similar problem, but is not working this time. Is my charger defective?

David, are you sure the battery needs charging? There needs to be a significant amount of depletion before the charger will start charging the battery. The symptoms you describe indicate the battery may not be sufficiently discharged to initiate charging.

If the battery will power one of your tools I suggest using the tool for a little while more and then attempting a charge.
